I live in the middle east and have bein sports. Most of the time there are arabic commentators. Belive me no matter how bad is the English commentary it's like a gold compared to the Arabic ones.
In the Arabic commentators you will have some who don't know how to pronounce players' names. Some who keep talking for the whole game without one second of silence as if you're listening to them on the radio not on TV. Then there are the Barcelona/real Madrid parties which are the worst commentators of them all because all they do is just talking about real Madrid or barca even if the match is in the Qatari league!
So be grateful for what you got
Now about the logo, there are 2 things :
1 - the bein bouncing logo: that's get sent from the source (the broadcasting unit itself) and appears every few minutes and acts as a watermark so any other medium can't record or broadcast the game.
2 - the random code : which appears as black characters and sometimes as white characters on black background. Those are unique numbers generated by each receiver so they appear on one screen only. ( client side). The unique number is used to identify the subscribers who share their broadcast with others illegally.. Like streaming them online. That way the channel moderators can identify which user is responsible for the streaming and sue them.
I've been watching bein for years and it really annoys me those stupid things appearing on screen but unfortunately in the middle east it's a monopoly for them so I got no other option
